Figure Lengend Snippet: Primary peripheral neutrophil and microglia interactions based on wild-type and knockout mice. (A) Western blotting images demonstrated the effect of SB431541 treatment on the activation status of the TGF-β signaling pathway in SAH regulated by AE. (B to G) Quantitative analysis of relative expression level changes in Alk1, Alk5, Smad1/5, Smad2/3, p-Smad1/5, and p-Smad2/3 in the AE-regulated ipsilateral cortex in SAH, with the treat of SB431541. n = 6. (H) Schematic diagram of coculture experiments between primary peripheral neutrophils and primary microglia. (I) Immunofluorescent staining of primary microglia from wt/ko mice cocultured with primary neutrophils from wt/ko mice for Lpl/Sec24a (red), Iba1 (green), and DAPI (blue). Scale bars, 10 μm. (J) Immunofluorescent staining of primary peripheral neutrophils from wild-type and knockout mice for Lrg1 (red), Ly6G (green), and DAPI (blue). Scale bars, 10 μm. (K) Western blotting images of primary microglia from wt/ko mice cocultured with primary neutrophils from wt/ko mice on pro-inflammatory and anti-inflammatory factors and TGF-β signaling pathway. (L to W) Quantitative analysis of relative expression level of IL-1β, IL-6, Nos2, IL-4, IL-10, Tgfb1, Alk1, Alk5, Smad1/5, Smad2/3, p-Smad1/5, and p-Smad2/3 in the primary microglia cocultured with peripheral neutrophils. n = 3. (X) Quantitative analysis of the proportion of Lpl+/Iba1+ cells in the immunofluorescent staining of primary microglia in the primary cell coculture experiment. n = 3. (Y) Quantitative analysis of the proportion of Sec24a+/Iba1+ cells in the immunofluorescent staining of primary microglia in the primary cell coculture experiment. n = 3. In (B) to (G) and (L) to (Y), data were represented as mean ± SD, and P values were calculated using one-way ANOVA with Tukey multiple comparisons. * P < 0.05, ** P < 0.01, *** P < 0.001. The original Western blot images are shown in Data . Detailed experimental data and statistical results, including F and P values for ANOVAs, are provided in Data to .
